Sebastian Stan gets together with Anthony Mackie while attending the 2014 Wizard World Chicago Comic Con held at Donald E. Stephens Convention Center on Sunday (August 24) in Chicago, Ill.

The 32-year-old actor and Anthony, 35, sat down for a special fan Q&A at the Captain America: The Winter Soldier panel where they dished about their characters and revealed some details about the upcoming third film.

At the event, Sebastian and Anthony did the ALS Ice Bucket Challenge together, though they did not pour ice water over their own heads. The guys used tiny dolls that resembled their superhero characters instead!

“Well…this man could snap me in half. Had to get a pic with this legend @louferrigno! #wwphillycc #louferrigno #realhulk #fistpumpapparently #drive495 hey @donsaladino I told him about bev’s,” Sebastian captioned an Instagram photo. Check it out below!
